3-Claims. 1

This invention relates to fasteners for securing marginal overlap portions of panels or roofing units toeach-other: and to a-framework or sheathing. The present improvement pertains to cliptype 'fastenershaving doubled-over portions provided withterminal penetrating pointsor proj ections.

An object of the-invention is to provide such a fastener adapted to savetime'and thereby materially reduce the cost of packing, shipping, handling, and laying commercial roofing of many types including roll roofing, individual shingles, and strip shingles. For convenience such roofin elements will be referred to as shingles.

Another object is to provide a fastener of the class described having a body portion so preformed that whenplaced on a shingle and struck with a roofers hammer it shall fly' up at one end, assuming a position in which it serves as an alinement gage for the next course of roofing, and from which it can be bent down nearly flatwise overtheitop face of an overlap shingle, either'by hand or with ahammer. When-thus bent down it can beset so as toclinch together the upper edge of an underlap shingle andthe lower edge of an overlap shingle.

Another object is to provide a roofing fastener that can be readily applied to the shingles or roll units at the shingle mill so .asfto'be ready for clinching when the shingle isput'in place o n'the sheathing.

This is .an application. repeating .a portion of an earlier application.filedJ-byme, and adding matternotdisclosed in said earlier case and also matter. disclosed, but, not claimed therein.

.My. copending application, Serial ,No. 589344,

of which this. isa continuation-impart, describes andolaims an improved fastener for .securing marginal underlap .and. overlap portions of roof.-

ing units andthelike to each other or to .a framework or sheathing.

-My copending application contains claims directed generally to the structure of roofing, fasteners characterizedby havingan elongatedbody that lies substantially .in a single .plane, .that is,

approximately fiat upon the face ofapiece-of roofing. It has fastening means for securing it to roofing pieces that are arranged in the usual manner, with zunderlap sand/overlap. Integral with the elongated body and intermediate its length, and projecting laterally or sidewise therefrom, is a member which upon being actuated by a hammer stroke, causes an end portion of the elongated body to rise up from its initial fiatwise position on the face of the roofing, into upstanding position whereit becomes an accurately alined stop-gage for the overlap portion of the roofinginthe next course.

In my,parentaapplication the laterally projecting member is described and claimed as being capable of flexing so as .to.. snap-one-end.in to upright position with a stroke of a roofingv hammer. .Thus the vbodyisbent so as tov extend over the top face of the overlap, piece. ,It then ,canlbe flattened down by afinalhammer blow.

My .present :invention, like that described in Serial vNo. 589,844, is provided witha laterally offset portion which, when struckwith, aroofeits hammer during the nailing operation on theroof, shifts theifree-end vof.gage,portion of thefastener upwards, bringing-it into positionifor alin-v ingthe nextupper. course of roofing. However, my eariier-nembod-iment assumes that position by deformation of. the metal of. the fastener; whereas the embodiment :set forth in the present. application attains-the same :result, not by deformingithe metal, but :by .giving the whole fastener a partial movement of-rotation about itslongitudinal :axis. That; is to. say, the same resultsas with the earlier fastener are attained, but by .a different. and novel, principle and mode: of operation.

-With :the foregoing Y and a certain other objects inview, which will-appearrlate-r in the'specifications, myiinvention comprises novel features 1. of construction and combinations of. parts described and claimedherein, which-will be better-under stood in the course of the following detailed description, referencebeing had to the accompanying drawings which'form apart of the specifications and --by which preferred typical embodiments are' illustrated.

'It' will 'be understood that various modifications may be resorted to within the scope aof-the..appended claims :without departing from themvention or sacrificing its advantages.

Fig. 9 is a small-scale cross-sectional view on line 99 of Fig. 8; and

Figs. 10 and 11 are plan views of modified forms of gage member, shank, and ofiset.

In a preferred form. illustrated in Figs. 1 to 9, my improved fastener comprises a shaft-like body portion which is substantially straight so it can lie fiat on the face of a piece of roofing. It has on one part, I, an end claw 2 which is recurved and also is laterally askew with respect to the part I, as shown, Figs. 1, 2, 5, presenting a clincher, 3.

Numeral 4 designates another portion of the body having at its end a hook-like member 5 which is situated in the same plane, B, A, Fig. 6, with the axis of the body parts I and 4. Part 5 preferably has a prong 6.

A member 1 projects laterally from the body I, 4, at a convenient point intermediate the claw 2 and the hook-like part 5.

Preferably, but not always necessarily, the outer extremity of projection I is formed with a lip 8 that extends downward, as shown, in two positions, disengaged from the roofing piece, in Fig. 6, and clinched thereto in Fig. 9. The laterally projecting member 1 is one of the operating features of my present improvement, by which hook 5 is shifted angularly, from the position Fig. 6 to the position Fig. 9, upon being engaged by the head of a roofing nail being driven through the roofing into the sheathing, as shown.

The nail head forces member I and its lip 8 to a firm anchorage on the roofing piece and in so doing partially rotates the body. That raises the hook-like part 5 up through a corresponding angle of rotation into substantially upright position. indicated by dotted lines in Fig. 6. The rotation of body I brings claw 2, Fig. 2, downward sidewise from the dotted position 3a to position 3. It is obvious that when the nail has been fully driven, as shown in Figs. 8 and 9, the nail fixes the fastener tight to the roof and also releases the end of clincher-claw 2 fromits original clinched position, at 3a, on the roofing piece, Fig. 2.

It will be understood that for purposes of shipments of roofing with my fasteners attached, as is also the case with the fastener device disclosed in my earlier application, the end 3 of claw 2, which preferably is a prong, was first hooked into the bottom face of the piece of roofing,as shown at 3a. Fig. 2, and at 3, Fig. 6. Thus the fastener was secured to the roofing for shipment, and for convenience in laying the roofing. The hook-like part 5'lies substantially fiatwise against the face of the roofing piece when the claw 2 and its pronged end 3 are clinched as and bring the in Fig. 6. Then the fastener as a unit occupies a minimum of shipping space.

When parts I and 8 are forced by the nail into the position shown in Fig. 9, and parts I and 4 have rotated, then the hook-like member 5 stands upright. ready to gage and guide the roofing pieces of the next tier to be laid.

In Fig. 6 the prong 3 lies in the plane represented by the line A that includes the axis of the body I, 4. The prong 8 on ofiset member 1 is in the plane C and the arm 5 and its prong 6 are in a plane represented by line B, and the upright position of arm 5 is shown by dotted lines, as already alluded to.

Thus it is seen that driving the nail rotates the body I, 4 and shifts the hook-like member 5 into an upright operative position where it is adapted to serve as a gage and aligning element. by which an overlap portion of a subsequently laid tier of roofing will be accurately located on the underlap and can be clinched thereto as shown in Figs. 3 and 8.

In Fig. 10 a modified form of the offset parts I and 8 is shown at la, and in Fig. 11 the offset is shown in the form of a loop lb through which the nail may be inserted. Any other appropriate form of offset, 1, may be employed provided it shall be adapted. to rotate the parts I and 4 when encountered by the head of a roofing nail being driven.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A fastener for roofing pieces comprising in combination a shaft-like partially rotatable body portion having at one end a claw recurved and askew and having at the other end a hook-like part situated in substantially the same plane that includes the axis of said body; said body having a laterally projecting member intermediate said claw and hook-like part and situated in a separate plane from either end of said body portion; said member adapted to shift angularly upon being engaged by the head of a roofing nail, and to shift said hook-like part into operative position for guiding, gaging, and alining an overlap portion of a subsequently laid tier of roofing.

2. A partially rotatable shaft-like body having at one end a recurved claw set askew; a hooklike member at the other end of the body; a projection extending laterally from said body intermediate the hook-like member and the claw; the hook-like member and lateral projection being arranged in a separate plane from either of said ends and constituting a positioning device adapted upon being actuated by a roofing nail in driving, to rotate the body and bring the hooklike member into substantially upright position; thus presenting a gage for alining an overlap of an upper tier of roofing with an underlap of a lower tier and for locating the outer portion of the hook-like member in position ready for use in clinching the said tiers together.

3. In a roofing fastener a rotatable bod having a clincher at one end; a hook-like member at the other end; and a projection on said body, situated in a separate plane from either end of said fastener.
